沉没成本效应是一种有趣的、众所周知的适应不良行为，在真实的生活中普遍存在，因此在经济学、心理学、组织行为学、政治学和生物学等多个学科中都有研究。然而，沉没成本效应背后的神经机制还没有明确建立，也没有他们的个人易感性的差异的影响。利用功能性磁共振成像，我们研究了由沉没成本沿着人类核心人格的测量引起的神经反应。我们发现，倾向于遵守社会规则和法规的人（在测量的宜人性和舒适性方面都很高）更容易受到沉没成本效应的影响。此外，这种行为观察强烈介导的沉没成本决策过程中的活动。在沉没成本下的决策过程中，也观察到了大脑皮层和外侧前额叶皮层之间的紧密耦合。我们的研究结果揭示了个体差异如何影响沉没成本下的决策，从而有助于更好地理解沉没成本效应的心理和神经机制。
The sunk cost effect, an interesting and well-known maladaptive behavior, is pervasive in real life, and thus has been studied in various disciplines, including economics, psychology, organizational behavior, politics, and biology. However, the neural mechanisms underlying the sunk cost effect have not been clearly established, nor have their association with differences in individual susceptibility to the effect. Using functional magnetic resonance imaging, we investigated neural responses induced by sunk costs along with measures of core human personality. We found that individuals who tend to adhere to social rules and regulations (who are high in measured agreeableness and conscientiousness) are more susceptible to the sunk cost effect. Furthermore, this behavioral observation was strongly mediated by insula activity during sunk cost decision-making. Tight coupling between the insula and lateral prefrontal cortex was also observed during decision-making under sunk costs. Our findings reveal how individual differences can affect decision-making under sunk costs, thereby contributing to a better understanding of the psychological and neural mechanisms of the sunk cost effect.
